Answer:

  (a)  x - y + 1 = 0

Step-by-step explanation:

One way to address multiple-choice questions is to try the answers to see what works.

For the lower left point (1, 2), the answer choices shown give ...

  x -y +1 = 1 -2 +1 = 0 . . . . . equation works

  -x -y +1 = -1 -2 +1 = -2 . . . doesn't work

  y -x +1 = 2 -1 +1 = 2 . . . . . doesn't work

The appropriate choice is ...

  x - y + 1 = 0

lamont read 313.5 pages of his book in 5 hours 30 minutes. if he reads at a constant rate, hiw many pages of his book did lamont
Rzqust [24]
Lets find out how many pages he can read in a minute:

313.5 pages in (60*5)+30 = x minutes, x = 330 minutes

313.5/330 = .95 pages a minute

1 hour is 60 minutes

.95 * 60 = 57 pages in an hour.

Edit:
cross multiply to find how many pages read in an hour

313.5 pages                                   x pages
--------                                       =    -----------------
5 hours 30 mins (330 mins)            60 mins


(313.5*60)/330 = 57
